At the Washington Auto Show, Cadillac boss Johan de Nysschen said that the experience GM learned from plug-in technology in cars like the Volt and Spark EV would be "applied across the spectrum of our company's portfolio"

No details were given, so it could mean something as vague as the start/stop technology will be applied, but I like to think it means they will add plug-in hybrid stuff across their lineup. This is likely in response to Mercedes announcement that they will put plugs on almost all of their vehicles in the nearby future.

There was also an announcement about GM asking the dealers that sell Cadillac alongside Chevrolet to create specialized "boutique locations" for the brand - perhaps to target Tesla's retail store locations?
